It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

D Terminology of Packaging and Distribution Environments. Unless otherwise indicated, it is intended that all reagents shall conform to the speci? An abnormal product lot may cause differences in testing response that throw off the expected time patterns. Link to Active This link will always route to the current Active version of the standard.

NOTE 1—The aetm for this practice cannot occur unless the vessel used as the environment container is vented so that pressure differences between the inside and the outside of the vessel can be balanced. For example, a given type of tape a speci? Immediately remove the sample rolls from the assembly. It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. This solution within the closed vessel both provides and controls the moisture content humidity within the vessel.

Use a volume the units will be cubic centimetres of water not less than that obtained by multiplying times times the vessel air volume in cubic metres. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. The practice does not provide for a conclusion within itself, but is for use in conjunction with appearance or physical property tests to follow the accelerated exposure.

A number in parentheses indicates the year of last reapproval. We do not expect this superimposed added variability effect to be great. This means that a measurement of precision for a physical property test on tape always has as one of its components the inherent variability between tape specimens. The practice does not provide for a conclusion within itself, atm is for use in conjunction with appearance or physical property tests to follow the accelerated exposure.

The environment in the vessel is satm on careful observation of the requirements of loading in relationship to vessel volume and liquid surface area asm accordance with Section 7. While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Therefore this conditioning does not always cause an increase in dispersion.

Include no more sample rolls than will displace one fourth of the air volume in the vessel. This is like the variability in any test method that we commonly term its precision. Aztm for Humidity Vessel in Oven procedure 7. A superscript epsilon e indicates an editorial change since the last revision or reapproval. There is no present experience to relate this accelerated exposure to responses of tape in applications where the tape is under a use stress.

This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. Originally approved in It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Historical Version s — view previous versions of standard. The extent of change for one physical property should be expected to be different than for another property and so would also relate to different natural aging time.

Aging reduces this inherent variability between specimens for some types of tape and some tests. It is an effect due to the small differences that occur in performing any step of a process. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM X Headquarters.

The vessel must meet the following requirements: Since it is seen as a change in the apparent variability of the physical property test results, we can relate it to the expected precision of the test by making the following statement: Last previous edition approved in as D — 89 TOP Related Posts.

The procedure is intended to simulate unwind tape either with a human hand, or with a tool or machine. This test is similar to ASTM D, however it is much simpler and designed to unroll the tape at low speeds. Several outer layers of tape should be unwound and discarded before beginning this test. Geometry: Rolls of tape are tested at a standard 1 inch thickness. The roll should be of consistent width throught the test.
